The present application claims the priority of and is a continuation-in-part of U.S. application Ser. No. 11/360,841 filed Feb. 23, 2006, the entire disclosure of which is hereby incorporated by reference.
The present invention relates to a combination trellis and tool system and to its methods of use and manufacture.
Depending upon their construction, known trellises can be used to support plant growth or to hold potted plants. Multi-legged trellises are known in the art. Exemplary one are disclosed in U.S. Pat. Nos. 6,895,712, 6,588,143, 6,453,606, 6,349,502, 6,088,956, 5,595,019, 5,179,799, 5,048,231, 4,019,280, 3,299,569, 3,264,783, 3,113,400, 3,088,245, 2,009,867, 1,617,494, 1,361,464, 897,006, 760,879, 601,691, 212,604, No. D459,492, No. D406,021 and others.
U.S. Pat. No. 5,412,905 discloses a trellis having three support rings, wherein the larger ring is at top, and the rings below decrease in size in order. U.S. Pat. No. D413,233 discloses a trellis system very similar to that of the '905 patent except that the order of ring sizes is reversed from top to bottom.
U.S. Pat. No. 5,174,060 discloses a trellis with two rings and three support legs. The larger ring is a located at the top and the smaller ring closer to the bottom. A helical coil connects the two rings.
U.S. Pat. No. 2,763,096 discloses a sectional three-legged trellis that includes three equally-sized support rings. Each ring is made up of plural apertures. The sections of the trellis are stackable by way of seats located in several of the apertures of each of the rings.
To prevent having to buy and install different support structures for plants in containers and plants in the ground, it would be advantageous to use the same structure for both a cage for hanging plant limbs, vines, branches, and the like, and a support for a plant container. Most known structures, however, cannot perform both functions.
The materials used to make many of the known trellises are also unstable, flimsy, and/or too flexible wire frames. For example, the wire structures frequently deform or the welds holding the wire structure together break during the application of downward force to fix the structure to the ground, during use, or and when the wire structure is pulled from the ground. Thus, many of the known trellises are of limited use.
As such, it may be appreciated that there continues to be a need for a trellis adapted to provide a plant container support designed to effectively accommodate various sized containers and provides sturdy reliable support. Additionally, there is a need to provide a sufficiently rigid trellis that can withstand the rugged handling associated with repeated insertion and removal from the ground.
Each of the known trellises has a limited scope of use due to its construction. None of the known trellis systems employ a tool that cooperates with the trellis to provide additional utility to the trellis.
The present invention seeks to overcome the disadvantages present in known trellis systems and/or to provide additional utilitarian features over those known systems.
The invention provides a multi-legged (multi-strut, multiple vertical support) trellis having a multi-purpose tool engaged therewith. The trellis is constructed with one, two or more (multiple) vertically spaced horizontal support rings. The first ring is engaged in a fixed or removable manner with one end of the support legs. The second ring, if present, would be spaced away from the first ring and located somewhere between both ends of the support legs to create a balanced and stable trellis. The second ring would be engaged with the legs in a fixed or movable manner. The legs are straight and angled toward each other to form a conical type of frame. The legs can be evenly or unevenly spaced about the circumference of each ring. The rings are adapted to provide to the legs resilience or resistance toward displacement, thereby creating a biasing means adapted to bias the legs toward the longitudinal axis of the trellis when the legs are displaced therefrom. The tool can provide additional stability to the trellis.
The tool is constructed of a rigid or semi-rigid material. It can be used in conjunction with a trellis having one, two or more horizontal supports or it can be used in place of a horizontal support in a trellis having one, two or more horizontal supports. For example, the tool might be used in place of the smaller second ring or to cooperate with it. In some embodiments, the tool is comprised of resilient molded plastic. The tool comprises a tray including three or more engagement means (e.g. slip-fit, snap-fit joints) by way of which it engages the legs of the trellis. The tool is slidable and dimensioned in such a manner so that it separates (distends) the ends of the legs away from one another as the tool is slid or placed towards the bottom ends of the legs. In other words, the diameter of the tool is smaller than the diameter of the upper ring when the trellis is stood upright. The tool optionally comprises a tip engager (coning tool) adapted to engage the ends of the legs to maintain them adjacent one another.
One aspect of the invention provides a trellis system comprising a trellis and a tool, wherein:
In some embodiments, the horizontal support has an outer perimeter radius larger than the radius of the tray or at least larger than the shortest lateral distance between leg engagement means of the tray and the center of the plane defining it. The tray can comprise the same number of leg engagement means as there are support legs in the trellis. The tray can be a plate or ring, and it can be any geometric shape such as, without limitation, a circle, oval, square, or rectangle.
In some embodiments, the trellis comprises two horizontal supports: an upper support engaged to the ends of the support legs, and a lower support engaged with the legs but at a location spaced away from the upper support. The lower support can have a smaller outer diameter, as measured along the plane defining the support, than the upper support. As a result the legs of the trellis run parallel to the longitudinal axis of the trellis; however, together with the horizontal support(s) they form a conical (or pyramidal) frame whereby one end of the legs is spaced farther apart than the other end of the legs. In other words, when in the upright position, the upper ends of the legs of the trellis are generally laterally spaced farther apart than the lower ends of the legs.
The horizontal supports are generally transverse to or perpendicular to the longitudinal axis of the legs and/or trellis. In some embodiments, the horizontal support is fixedly engaged to the support legs. In other embodiments, it is slidably and/or removably engaged with the support legs. At each occurrence, the horizontal support is independently fixedly, slidably or removably engaged with corresponding support legs.
The legs can be evenly or unevenly spaced radially about the circumference of the horizontal support(s). At each occurrence, the individual legs are independently selected from the group consisting of unitary leg or segmented leg. The invention includes embodiments, wherein all of the legs are unitary legs or all of the legs are segmented legs. The invention also includes embodiments, wherein the legs comprise a combination of at least one unitary leg and at least one segmented leg.
A segmented leg of the invention generally comprises two or three linear segments that are engageable end-to-end with engagement means to form a leg support.
Another aspect of the invention provides a break down type trellis system comprising a break down type trellis and a tool according to the invention. In some embodiments, the break down type trellis comprises:
an upper horizontal support comprising a ring body and plural first leg segment-engagement means;
a lower horizontal support comprising a ring body and plural second leg segment-engagement means;
plural extended upper leg segments each comprising upper and lower engagement means, wherein the upper engagement means is adapted to engage with the first leg segment-engagement means and the lower engagement means is adapted to engage with the second leg segment-engagement means; and
plural extended lower leg segments each comprising upper engagement means, adapted to engage with the second leg segment-engagement means and/or lower engagement means of corresponding upper leg segments.
In some embodiments, the upper leg segment comprises: a) a body comprising a rod, tube or combination thereof; b) threaded upper engagement means; c) threaded lower engagement means; d) an upper (distal) abutment surface adjacent the upper engagement means; e) a lower (distal) abutment surface adjacent the lower engagement means; f) lower engagement means comprising a collar or extended section narrower in diameter than an adjacent abutment surface and disposed between threaded engagement means and the lower abutment surface; g) at least one collar between each end of the body and the upper and lower engagement means; h) male threaded upper engagement means and/or lower engagement means; i) female threaded upper engagement means and/or lower engagement means; and/or j) two right-hand threaded engagement means, two left-hand threaded engagement means, or at least one of each.
In some embodiments, the lower leg segment comprises: a) a body comprising a rod, tube or combination thereof; b) threaded upper engagement means; c) an upper (distal) abutment surface adjacent the upper engagement means; d) upper engagement means comprising a collar or extended section narrower in diameter than an adjacent abutment surface and disposed between threaded engagement means and the upper abutment surface; e) at least one collar between the upper end of the body and an the upper engagement means; f) male threaded upper engagement means; g) female threaded upper engagement means; and/or h) right-hand threaded engagement means or left-hand threaded engagement means.
In some embodiments, the upper horizontal support comprises: a) three to six first leg segment-engagement means; b) first leg segment-engagement means that are substantially similar; c) threaded first leg segment-engagement means; d) right-hand threaded or left-hand threaded first leg segment-engagement means; and/or e) first leg segment-engagement means comprising a lower abutment surface.
In some embodiments, the lower horizontal support comprises: a) three to six second leg segment-engagement means; b) second leg segment-engagement means that are substantially similar; c) threaded second leg segment-engagement means; d) pass-through second leg segment-engagement means; e) right-hand threaded or left-hand threaded second leg segment-engagement means; and/or f) second leg segment-engagement means comprising a lower abutment surface, an upper abutment surface, or both.
Another aspect of the invention provides a break down type trellis comprising:
an upper horizontal support comprising plural male engagement means having lower ends;
a lower horizontal support comprising plural male engagement means having upper and lower ends;
plural upper leg segments the ends of which comprise female engagement means; and
plural lower leg segments at least one end of which comprise female engagement means.
In some embodiments of the invention, the upper leg segment comprises: a) an inner tube substantially coextensively surrounded by an exterior tube (or coating); b) distal ends that serve as upper and lower engagements means, respectively; c) female upper engagement means adapted to engage with the male engagement means of the upper horizontal support such that a pressure fit joint is formed; and/or d) female lower engagement means adapted to engage with an upper first end of male engagement means of the lower horizontal support such that a pressure fit joint is formed.
In some embodiments, the lower leg segment comprises: a) an inner metal tube substantially coextensively surrounded by an exterior tube (or coating); b) upper female engagement means, which is adapted to engage a lower end of male engagement means of the lower horizontal support such that a pressure fit joint is formed.
The tool optionally comprises a tip (end) engager adapted to engage the ends of the legs that are opposite the end engaged with the horizontal support.
These and other aspects of this invention will be apparent upon reference to the following detailed description, examples, claims and attached figures.
The following drawings are given by way of illustration only, and thus are not intended to limit the scope of the present invention.
A trellis system of the invention provides unexpected advantages over other trellises. The trellis system is portable and can be utilized directly in the lawn and garden landscape/terrain industry. It can be installed into an existing potted plant or base unit, to be topped of with other greenery or flowering plant, pumpkin, gazing ball or any round or convoluted decorator piece to create a decorative display. The trellis system can also provide a means to display plant in location where they would otherwise not be displayable. For example, a trellis with a potted plant could be installed along a sidewalk or pool or other such location where it would difficult to display a hanging potted plant. The trellis can also be installed in inclined or level surfaces.
The bottom ends can be adapted to engage with and penetrate into the earth to anchor the plant support to the earth. The trellis can be shaped so as to provide support to plants growing out of the ground and to support plant containers (pots) that are placed within the plant cage interior. The trellis can be shaped to facilitate the stacking of a plurality of the plant cages for storage.
A trellis system of the invention comprises a combination of a trellis and a tool. The trellis can comprise three or more vertical supports (legs) and one or more horizontal supports (support rings). The trellis system (1) of
The legs of the trellis are fixedly engaged with and evenly spaced about the outer perimeter of the upper horizontal support ring. However, the legs can be unevenly spaced about the perimeter of the ring, and the legs can be engaged with the inner perimeter, rather than the outer perimeter, of the ring.
The tool (4) is depicted engaged with the legs at a location below the lower ring or between the lower ring and the lower ends of the legs. In this use, the tool serves to distend the legs away from each other or away from the longitudinal axis of the trellis during installation of the trellis into soil, for example. The closer the tool is towards the lower end of the legs, the more it distends the legs. However, following installation of the trellis with the tool, the tool can be placed between the two rings (2 a, 2 b) or merely on top of the lower ring, wherein it can serve to support a flowerpot, candle, gazing ball or other decorative garden ornaments, for example.
Since the legs are resistant toward distension from the longitudinal axis of the trellis, by virtue of there engagement with one or more horizontal support rings, they spring back toward their original orientations following disengagement of the tool from the lower portion of the trellis. In this way, the legs grasp the soil (and root system, if present) within which they are placed thereby providing greater stability to the trellis.
The trellis system (5) of
A support leg is an elongated support member such as a pole, tube, wire, or rod. The length of each of the legs in a trellis will generally be about the same within about 15% of the average length; however, the invention also includes embodiments wherein one or more of the legs has a different length than the other leg(s) in the trellis. The diameter or thickness of the legs can be adapted as needed to provide the desired level of strength. The legs of the trellis are of sufficient strength to be drivable by hand into the ground without collapse of the trellis or without excessive bending of the legs. They are also sufficiently strong to bear the weight of the plant(s) or plant pot(s) that the trellis is holding. The legs are of sufficiently flexible to permit at least some flexing by hand so as to facilitate operation of the combination tool. For example, after flexing, the legs preferably have sufficient resiliency to spring back to their original position thereby grasping the matrix (soil, rocks, gravel, sand, etc.) within which the trellis is installed. This flexing feature is useful for improving the stability of an installed trellis.
Any sturdy material can be used to prepare a trellis and/or tool according to the invention. The material(s) used to make the trellis and tool are independently selected at each occurrence. Suitable materials include, by way of example and without limitation, iron, steel, plastic-coated steel, aluminum, powder coated steel, fiberglass, metal, wood, plastic, polyurethane, polypropylene, and other rigid or even semi-flexible material or combination of materials. One of the proposed embodiments includes a plastic sleeve encasing a hollow metal tube or encasing a folded and/or rolled metal sheet. In some embodiments, the leg comprises hot rolled round rod (e.g. metal, iron, steel), which can be 3/16″ to ⅜″ or about ¼″ in diameter. In some embodiments, the horizontal support comprises hot rolled round rod (e.g. metal, iron, steel), which can be 3/16″ to ⅜″ or about ⅜″ in diameter. Depending upon the material used to make the tool, the thickness of the tray and/or end engager can be varied.
The surface of the legs can be adapted to vary the frictional engagement with the tool. The surface of the legs can be smooth, semis-smooth or rough (textured). Exemplary rough surfaces include, without limitation, a knurled, bumpy, gritty, sandy, jagged, stepped, variably raised, fluted and other surface textures typically used for such purpose. Exemplary surfaces are depicted in
The tool of the invention optionally comprises an end engager (or coning tool). The end engager is adapted to engage the legs at their end or at a location near the end.
The end engager will typically comprise the same number of engagement means as there are legs on a corresponding trellis. The end engager is engaged with the ends of the legs by compressing the ends of the legs together and then sliding the engager into place. The resulting conical or pyramidal frame trellis can then be used in the inverted position (small end upwards) as a frame onto which decorative items such as grapevine, foliage, greenery, live florals, silk, and other ornaments can be hung, draped, wrapped, or otherwise attached. A tree-topper, star ball or other such ornaments can be placed onto the frame.
The horizontal supports are arranged in a vertically spaced relation along the length of the legs between the top and bottom ends of the legs. When three or more horizontal supports are included, they can be longitudinally spaced evenly or unevenly along the length of the legs. In one embodiment, the plurality of horizontal supports can be two or more rings that are concentric around a common vertical central axis, e.g. the longitudinal axis of the trellis. These horizontal rings have progressively differing central opening diameters, i.e. the inner diameter of the ring as measured along the plane defining the ring. The central opening diameters of the rings increase as the rings can be arranged along the length of the legs with the bottom or lower most ring having a smallest central opening diameter and the top or upper most ring having a largest central opening diameter.
The diameter of the central hole in the horizontal supports can vary as needed. In one embodiment, the diameter of the central hole is adapted to accommodate standard flower (plant) pot sizes used in the nursery industry, e.g. pots having a 4″ to 24″ diameter.
In one embodiment of the trellis, the legs extend upwardly generally parallel to the vertical central axis from their bottom ends to the bottom or lower most ring. This upright, vertical orientation of the bottom ends of the legs can facilitate their insertion into the ground without bending. The legs then diverge outwardly from the vertical central axis as the legs extend upwardly from the bottom ring to their top ends.
The horizontal supports of the trellis are depicted as being circular or oval, when depicted from a plan view. However, they can also be square, rectangular, pentagonal, hexagon or other geometric shape.
The combination tool (10) depicted in bottom plan view in
The engagement means of the tray can be adapted to be slidable along the surface of the legs with which they engage. If the legs have a textured surface, then engagement means can be adapted to cooperate with the textured surface of the legs to enhance frictional engagement between the engagement means and the leg.
In this embodiment, the radius of the tray (11) as measured from the outer perimeter (19 c) of the tray to the center (19 b) of the plane defining the tray is larger than the radius of the horizontal support ring (16) as measured from the outer perimeter (16 a) of the ring to the center (16 b) of the plane defining the ring. The radius of the engagement means (14 a-14 c) as measured from the innermost proximal surface (19 a) of the engagement means to the center (19 b) of the plane defining the tray approximates or is smaller than the radius of the horizontal support ring (16) as measured from the outer perimeter (16 a) of the ring to the center (16 b) of the plane defining the ring.
The end engager comprises three apertures (17 a-17 c) that serve as leg engagement means by way of which the engager can be attached to the ends of three respective legs. The apertures are depicted as being bored in an angled direction, the angle being from 3 to 15 degrees off of an axis perpendicular to the plane through which the apertures pass. The angle of the aperture approximates the angle of the legs of trellis when it is configured to form a conical or pyramidal frame. The end engager is attached to the tray by way of breakable elements (18 a-18 c). In some embodiments, the end engager comprises the same material(s) that the tray comprises. In other embodiments, one or more of the materials are different. The inner diameter of the apertures approximates the outer diameter of the legs to which they are adapted to engage.
The combination tool (20) of

The combination tool (35) of
The tool of the invention optionally includes an end engager. The tools (41, 42) depicted in
The trellis system of the invention is used to support plant growth and/or to support one or more plant pots.
In a like manner, the trellis system can be used to install a trellis into the ground. The tool is engaged with the legs of the trellis at a position below the lowest ring and slid downwards to distend the ends of the legs from each other. The trellis is then pressed into the soil, and the tool is raised to allow the legs to converge towards each other thereby compressing the soil between the legs of the trellis. The tool of the invention thus facilitates installation of frame-type trellis on the one hand and provides a more firmly installed trellis on the other hand. The trellis can also be placed in other bases, besides soil, for other occasions. For example, a Styrofoam® filled container can be used as the base thereby making the entire unit light weight and easy to transport.
The tool can be designed to support standard nursery container hanging baskets and pots. After installation of the trellis, the tray portion of the tool can be used as a support for additional items such as a candleholder, lantern holder, flowerpot holder, vase, gazing ball, birdhouse, bird feeder and other items.
The potting stacking feature of the trellis system is advantageous as it permits drainage from the upper plant(s) to pass through to the lower plant(s). In addition, the plants are elevated to multi-level heights to enhance the aesthetic appearance of landscape.
A leg of the trellis system can be unitary or segmented in construction. By unitary leg is meant a full-length leg having a fixed length and comprising a single lengthwise section of material from which the leg is made. By segmented leg is meant a leg comprising at least two engageable sections that together form a single full-length leg having a length greater than the length of either individual section. The segments are engaged on an end-to-end basis by temporary or permanent engagement means to form the full-length leg.
The sections of a segmented leg can have the same or different dimensions. For example, a first section can be longer, shorter or approximately the same length as the second section.
The leg segment (90) of
The body of an upper section can be a rod (or tube, 81), tube or combination thereof (101, 102). The leg segment 100 (
While it is necessary for each end of the upper leg segment to comprise engagement means, it is not necessary that each engagement means be male, as depicted in
The lower leg segment can be made in various constructions. The lower leg segment (120) of
The upper and lower horizontal supports of the invention will vary in construction according to the leg(s) with which they are adapted to engage.
The lower horizontal support (150) depicted in
Instead of pass-through engagement of the upper leg segment with the engagement means (154), the lower horizontal support (160) can comprise threaded engagement means (163). In this embodiment, the threaded engagement means (83) of leg segment (80) will be threaded into the threads (165) until the lower abutment surface (82) of the collar (85) contacts the upper abutment surface (166) of engagement means (163), whereby a portion of the threaded engagement means (83) will extend beyond the lower abutment surface (167) such that it can engage with engagement means (123), for example, of lower leg segment (120).
One or more sections of a segmented leg can be engaged with one or more horizontal supports of a trellis system. In some embodiments, the first section is engaged with a first horizontal support, and the second section is engaged with a second horizontal support.
In the embodiment of
An alternate embodiment of the trellis system (170) of the invention, as depicted in
The break-down construction of trellis systems (72, 170) is highly advantageous as it permits reduction in packaging and shipping costs as compared to the packaging a shipping costs of a trellis system not specifically designed to break down, e.g. the trellis systems of
